About this place

Located at the very end of the road to Harts Pass, this is one of the highest elevation trailheads in Washington State. Access is via a very narrow and steep road with sharp drop-offs. Provides access to Slate Peak Lookout and the West Fork Pasayten River Trail #472 within the Pasayten Wilderness. Very small parking area, not suitable for trailers or RVs. A fee is charged. From Winthrop, take State Route 20 west for 13 miles, turn right on paved Lost River Road and travel 7.5 miles. Then continue on gravel Forest Road 5400 to Harts Pass then turn right and follow spur road uphill to pass Pacific Crest Trailhead (at first switchback), Slate Pass (at second switchback) to arrive at Slate Peak trailhead at the gate near end of the road.
